Kepler is a Discovery-class mission designed to determine the frequency of Earth-size planets in and near the habitable zone (HZ) of solar-like stars. The instrument consists of a 0.95 m aperture photometer designed to obtain high precision photometric measurements of >100,000 stars to search for patterns of transits. The focal plane of the Schmidt-telescope contains 42 CCDs with a total of 96 megapixels that cover 100 square degrees of sky.
Both the Schmidt corrector and 1.4 m aperture primary mirror have been fabricated and polished. All 50 CCD detectors have been delivered, tested and found to perform better than required, and are now being mounted in modules to be installed in the focal plane. Measurements of the ability of the first module to detect transit amplitudes expected from Earth-size planets are scheduled to start this month. A preliminary catalog classifying 11 million stars in the FOV has been produced. The science descope that replaced the articulated antenna with a body-fixed antenna still provides performance above the baseline design. A concise description of the current mission design and expected science results are presented.
